Easy Robot Arm (SG90 servos & now steppers too) UPDATED 03/21

prusaprinters

<p>Designed to need only the things that came with your SG90s(and maybe your 28BYJ-48 stepper too...), tried to make it easy to print, minimize number of pieces(though there are still a few), difficulty of scaffolding removal, etc.</p> <p>All motors and components are hot-swappable!</p> <p>Fusion and Step files included, for those that want.</p> <p>Especially pleased with the way the screw-caps hold and allow rotation.</p> <p>Ideas:</p> <p>1) Unless you have some servos with good torque, maybe use the 60mm arms only.<br/> 2.) Pic of little red elastic bands in the joints to dampen some of the vibrations.</p> <p>UPDATED 8 Mar 2021</p> <p>1.) Servo struggling to survive the lower motor position, adapter plate and pin added for 28BYJ-48 stepper motor.<br/> 2.) Offaxis head mounts added to bring gripper closer to the last arm pivot point.<br/> 3.) Various minor mods for strength and usability.</p> <h3> Print Settings</h3> <p><strong>Printer:</strong></p> <p>FULSUN i3 clone(modified)</p> <p><p class="detail-setting rafts"><strong>Rafts: </strong> <div><p>No</p></div><strong>Supports:</strong></p> <p>Yes</p> <p><p class="detail-setting resolution"><strong>Resolution: </strong> <div><p>0.2mm</p></div><strong>Infill:</strong></p> <p>10% Gyroid</p> <p><strong>Filament:</strong> ESUN3D PLA Light Blue <br/> <p class="detail-setting notes"><strong>Notes: </strong> </p><div><p>Might want to keep the print light, even as low as 5% and 2 perimeters, the SG90s might struggle with a heavy printed claw section.</p></div></p> </p></p> Category: Robotics
